Two people, one with a mass of 70kg and one with a mass of 45kg, sit on 5-kg frictionless cars that are initially at rest on a flat surface. The lighter person pushes on the more massive person, causing the latter to accelerate at a rate of 1.0m/s^2 toward the east. What are the magnitude and direction of the lighter person's acceleration vector?
